Including: Microbial degradation: microorganisms cultivated by special technical means, or using naturally existing microbial communities, take in, decompose and metabolize organic matter, nitrogen, phosphorus and other pollutants in wastewater as nutrients, and transform them into harmless or low-toxic substances; biofilm technology: biofilm is formed on the surface of solid media, and the microorganisms on the biofilm efficiently adsorb and degrade pollutants in wastewater. For example, MBR (membrane bioreactor) technology uses this principle.

[0003] Prior art, for example, invented a microbial sewage treatment pool, application number CN201910928547.0. By changing the oxygen discharge position, the microbial community migrates, which can promote the mutual communication between the various microbial communities, so as to promote the reproduction of protozoa and micro-animals in different microbial communities, produce better offspring to improve the ability to decompose pollutants in sewage.

[0004] At present, there is still a lack of equipment that can conveniently combine microbial degradation with biofilm technology, so that sewage can be treated in the MBR membrane area for a period of time and fully contact with the MBR membrane, and then contact with the microbial community to achieve treatment, so as to achieve environmentally friendly treatment of sewage and improve sewage treatment efficiency.

[0005] Therefore, in view of the above problems, a sewage environmental protection treatment equipment based on microbial reaction is proposed to solve the above problems. Summary of the invention

By utilizing the impact of water flow on the impeller shaft, the power bevel gear rotates, and then the I-shaped plate drives the piston to move, so that oxygen-enriched air is pressurized and ejected. The exhaust pipe is located at the lower part of the storage tank, so that the air has a large movement distance in the water, which is convenient for the sewage to fully contact with the air and the box is in an oxygen-enriched state. The I-shaped plate reciprocates to contact the falling sewage, which hinders the flow of sewage. The water expands on the support plane and then flows into the storage tank, increasing the air residence time and the contact area with the air. The oxygen-enriched sewage contacts the MBR membrane on the partition of the water wheel, which is convenient for treatment.

[0009] As an optimization, the bracket is connected to two groups of symmetrical middle vertical rods, each of which is rotatably connected to a stirring plate, each of which is connected to a symmetrical straight groove rod, the bracket is connected to a symmetrical round block, the symmetrical middle guide rods pass through the corresponding round blocks, the symmetrical middle guide rods are connected to round head rods, each of which is connected to one end of a lower spring, the symmetrical lower springs are respectively encircled by the corresponding middle guide rods, the symmetrical lower springs are respectively connected to the corresponding round blocks, the lower end of the impeller shaft is connected to an eccentric circular block, the symmetrical round head rods contact the eccentric circular blocks, each of which is connected to a T-axis, and the two ends of the circular axis of the symmetrical T-axis are respectively arranged in the groove of the corresponding straight groove rod. By adopting a lower spring and using the eccentric circular block to contact the round head rod, when sewage is treated, the eccentric circular block rotates to realize the swing of the stirring plate, and the two stirring plates swing asymmetrically, so that the sewage flows and contacts the MBR membrane on the partition of the water wheel, achieving full contact between the two and better treatment effect.

[0010] As an optimization, it also includes a transmission assembly, which includes symmetrical transmission gears, the symmetrical transmission gears are respectively connected to the inverted T-plates by bearings, each of the transmission gears is respectively engaged with a gear ring, each of the gear rings is respectively connected to the water wheel, the symmetrical inverted T-plates are respectively provided with outer straight grooves, each of the outer straight grooves is respectively provided with outer round rods, each of the outer round rods is respectively connected to the corresponding inverted T-plates, each of the transmission gears is respectively connected to the middle turntable, and the edge of each middle turntable is respectively connected to one end of the power connecting rod by rotation, the bracket is connected to symmetrical sliders, the symmetrical sliders are respectively arranged in the corresponding outer straight grooves, the symmetrical outer round rods respectively pass through the corresponding sliders, and the other end of the symmetrical power connecting rod is respectively connected to the corresponding slider by rotation.

Moreover, after the water wheel rotates, the primary treatment assembly is at the lowest end of its stroke and at the center of the storage tank, which is convenient for sewage treatment.

The MBR membrane plate is in an oxygen-rich box and moves in the height direction. When the block is in the sink, the sink is sealed and the MBR membrane plate is fully in contact with the sewage. Compared with the existing method of directly placing the MBR membrane plate on the lower side of the drain pipe, the treatment effect is better. After a period of contact with the sewage, the block is separated from the sink to achieve the discharge of oxygen-rich sewage in the box. In addition, due to the addition of oxygen-rich air, its pressure is relatively larger than that of the aerobic tank, and the sewage is pressurized and sprayed out, which intensifies the movement of sewage in the aerobic tank and impacts the active mud layer containing aerobic bacteria, so that the microbial community migrates accordingly, which can promote the mutual communication between the microbial communities, so as to promote the reproduction of protozoa and micro-animals in different microbial communities, and produce more excellent offspring to enhance the ability to decompose pollutants in sewage.

[0013] As an optimization, it also includes a pool oxygenation component, which includes a group of main pipes, each of which is provided with a group of air outlets on the upper part, each of which is fixedly connected to an air intake vertical pipe, and each of which is connected to a guide cross bar at both ends, and a symmetrical guide base plate is connected in the aerobic pool, each of which passes through the corresponding guide base plate, and each of which is connected to a mounting long plate on one side, and the mounting long plate is connected to a symmetrical lower vertical rod, and the symmetrical outer circular blocks are respectively connected to one end of the power inner rod, and the other end of the symmetrical power inner rod is respectively connected to the corresponding lower vertical rod.

[0014] As an optimization, a cleaning component is also included, which includes a group of counterweights, symmetrical guide thin rods are connected to both sides of each partition of the water wheel, the water wheel is provided with a group of evenly distributed symmetrical inner straight grooves, each inner straight groove is provided with an inner round rod, each inner round rod is connected to the water wheel, each inner straight groove is provided with a corresponding counterweight, each inner round rod passes through the corresponding counterweight, each counterweight is connected to the water wheel through an upper spring, each upper spring is respectively sleeved with the corresponding inner round rod, each counterweight is respectively connected to one end of the symmetrical inner connecting rod, the other end of each inner connecting rod is respectively connected to the inner mounting block, each inner mounting block is respectively connected to the brush plate, and each guide thin rod passes through the corresponding brush plate. The gravity of the counterweight, the elastic force of the upper spring and the centrifugal force generated when the water wheel rotates are used to realize the movement of the brush plate along the surface of the MBR membrane on the partition of the water wheel to clean the MBR membrane on the partition of the water wheel.

[0015] As an optimization, the main shaft is connected to the driven gear, the box is connected to the motor, the output shaft of the motor is connected to the driving gear, and the driving gear meshes with the driven gear. The rotation of the water wheel is achieved by adopting gear meshing and driven by the motor. The effects provided in the summary of the invention are only the effects of the embodiments, rather than all the effects of the invention. The above technical solution has the following advantages or beneficial effects: 1. This device stores sewage in a box for a period of time, allowing the sewage to contact with the MBR membrane for a period of time, to achieve the first treatment of sewage. An active mud layer containing aerobic bacteria is placed in the aerobic pool to decompose pollutants in the sewage, to achieve the second treatment of sewage, to achieve secondary microbial treatment of sewage, and to organically combine microbial degradation and biofilm technology to achieve environmentally friendly treatment of sewage.

[0016] 2. When the water wheel of the device rotates, the primary treatment component moves as a whole to avoid the contact between the primary treatment component and the partition of the water wheel and cause damage to the equipment. Moreover, after the water wheel stops rotating, the primary treatment component is at the bottom of its stroke and in the center of the storage tank. The exhaust pipe is located at the lower part of the storage tank, so that the air moves a large distance in the water, which is convenient for the sewage to fully contact with the air, so that the box is in an oxygen-rich state. The I-shaped plate reciprocates to contact the falling sewage, which hinders the flow of sewage. The water spreads on the support plane and then flows into the storage tank, increasing the air retention time and the contact area with the air. The oxygen-rich sewage contacts the MBR membrane on the partition of the water wheel, which is convenient for treatment. When the block is used to treat the lower sink, the lower sink is sealed, the MBR membrane plate is fully contacted with the sewage, the block is separated from the lower sink, and the oxygen-rich sewage in the box is discharged. Moreover, due to the addition of oxygen-rich air, its pressure is relatively large compared to the aerobic pool, so that the sewage is pressurized and ejected, so that the movement of the sewage in the aerobic pool is intensified, and the active mud layer containing aerobic bacteria is impacted.

[0017] 3. When the water wheel of the device rotates, the position of the air outlet changes, and oxygen-rich air is discharged. The change in the oxygen discharge position and the impact of the oxygen-rich sewage discharge in the box cause the microbial community to migrate, which can promote the mutual communication between the various microbial communities, so as to promote the reproduction of protozoa and micro-animals in different microbial communities, produce more excellent offspring, and enhance the ability to decompose pollutants in sewage.

The position of the air outlet 26 changes to discharge oxygen-enriched air. By changing the location of oxygen discharge, the microbial community will migrate accordingly, which can promote the mutual communication between the various microbial communities, so as to promote the reproduction of protozoa and micro-animals in different microbial communities, produce better offspring and enhance the ability to decompose pollutants in sewage.

[0044] The workflow of this embodiment is: A ventilation pipe is used to connect to an oxygen-enriched air source, and the ventilation pipe is connected to the air intake vertical pipe 24 respectively.

[0045] The outer circular block 49 drives the power inner rod 42 to swing, the power inner rod 42 drives the lower vertical rod 21 and the installation long plate 22 to move, the installation long plate 22 drives the guide cross bar 23 to move along the guide bottom plate 11, the guide cross bar 23 drives the main pipe 25 and the air intake vertical pipe 24 to move back and forth, the position of the air outlet 26 changes, and oxygen-rich air is discharged. The change in the oxygen discharge position causes the microbial community to migrate, which can promote the mutual communication between various microbial communities, so as to promote the reproduction of protozoa and micro-animals in different microbial communities, produce more excellent offspring to improve the ability to decompose pollutants in sewage.

[0046] Embodiment 5: This embodiment is further elaborated on the basis of Embodiment 1, 2, 3 or 4, and further includes a cleaning assembly 6, the cleaning assembly 6 includes a group of counterweights 65, each of the partitions of the water wheel 47 is connected to symmetrical guide thin rods 410 on both sides, the water wheel 47 is provided with a group of evenly distributed symmetrical inner straight grooves 411, each of the inner straight grooves 411 is provided with an inner round rod 412, each of the inner round rods 412 is connected to the water wheel 47, and each of the inner straight grooves 411 is provided with a corresponding counterweight 65, each inner rod 412 passes through the corresponding counterweight block 65, each counterweight block 65 is connected to the water wheel 47 through the upper spring 64, each upper spring 64 is respectively sleeved on the corresponding inner rod 412, each counterweight block 65 is respectively rotatably connected to one end of the symmetrical inner connecting rod 63, the other end of each inner connecting rod 63 is respectively rotatably connected to the inner mounting block 61, each inner mounting block 61 is respectively connected to the brush plate 62, and each guide thin rod 410 passes through the corresponding brush plate 62. The brush plate 62 moves along the surface of the MBR membrane on the partition of the water wheel 47 by utilizing the gravity of the counterweight block 65, the elastic force of the upper spring 64 and the centrifugal force generated when the water wheel 47 rotates, so as to clean the MBR membrane on the partition of the water wheel 47.

[0047] The workflow of this embodiment is: Since the counterweight 65 has a large mass, as the water wheel 47 rotates, the counterweight 65 moves along the inner circular rod 412 in the inner straight groove 411, the counterweight 65 drives the upper spring 64 to move, the counterweight 65 drives the inner connecting rod 63 to swing, the inner connecting rod 63 drives the inner mounting block 61 to move, the inner mounting block 61 drives the brush plate 62 to move along the guide thin rod 410, and the brush plate 62 cleans the MBR membrane on the partition of the water wheel 47.

[0048] This device achieves the first treatment of the sewage by storing the sewage in the box 32 for a period of time, allowing the sewage to contact with the MBR membrane for a period of time, placing an active mud layer containing aerobic bacteria in the aerobic pool 1 to decompose the pollutants in the sewage, achieving the second treatment of the sewage, achieving secondary microbial treatment of the sewage, and organically combining microbial degradation and biofilm technology to achieve environmentally friendly treatment of sewage.

[0049] When the water wheel 47 of the device rotates, the primary treatment component 5 moves as a whole, avoiding damage to the equipment caused by the contact between the primary treatment component 5 and the partition of the water wheel 47. Moreover, after the water wheel 47 stops rotating, the primary treatment component 5 is at the lowest end of its travel, at the center of the storage tank. The exhaust pipe 516 is located at the lower part of the storage tank, so that the air moves a large distance in the water, which is convenient for the sewage to fully contact the air, so that the box body 32 is in an oxygen-rich state, and the I-shaped plate 520 reciprocates to contact the falling sewage, which hinders the flow of sewage. The water expands on the plane of the bracket 56 and then flows into the storage tank, increasing the air retention time and the contact area with the air. The oxygen-rich sewage contacts the MBR membrane on the partition of the water wheel 47, which is convenient for treatment. When the block 82 is processing in the lower water tank 38, the lower water tank 38 is sealed, and the MBR membrane 83 is fully in contact with the sewage. The block 82 is separated from the lower water tank 38, and the oxygen-rich sewage in the box body 32 is discharged. Moreover, due to the addition of oxygen-rich air, its pressure is relatively larger than that of the aerobic tank 1, and the sewage is pressurized and ejected, which intensifies the movement of the sewage in the aerobic tank 1 and impacts the active mud layer containing aerobic bacteria.

[0050] When the water wheel 47 of the device rotates, the position of the air outlet 26 changes, and oxygen-rich air is discharged. The change in the oxygen discharge position and the impact of the oxygen-rich sewage in the box 32 when it is discharged cause the microbial community to migrate accordingly, which can promote the mutual communication between the various microbial communities, so as to promote the reproduction of protozoa and micro-animals in different microbial communities, produce more excellent offspring, and enhance the ability to decompose pollutants in sewage.
